Abstract: The synthesis of the Cu-borate complexes [(6Mes)Cu(HBR<subscript>3</subscript>)] featuring the unusual [HBEt<subscript>3</subscript>]<superscript>−</superscript> ( 5) and [HB(C<subscript>6</subscript>F<subscript>5</subscript>)<subscript>3</subscript>]<superscript>−</superscript> ( 6) ligands is described. Experimental and computational studies show both compounds feature a direct Cu-H interaction, but that while 5 is two-coordinate, 6 displays an additional, stabilizing Cu-C<subscript>ipso</subscript>(C<subscript>6</subscript>F<subscript>5</subscript>) interaction.
